Here are some examples of collisions management:

```
//Defines two points with its coordinates:
var myPoint = { x: 20, y: 30 };
var myPoint2 = { x: 30, y: 50 };
//Distance between two points:
CB_console("The distance between 'myPoint' and 'myPoint2' is: " + CB_Collisions.getDistancePoints(myPoint.x, myPoint.y, myPoint2.x, myPoint2.y));
//A point and a DOM element (considered a rectangle):
var element = CB_Elements.id("my_element"); //Equivalent to document.getElementById("my_element").
if (CB_Collisions.isPointOverElement(myPoint.x, myPoint.y, element)) { CB_console("The point is over the element whose ID is 'my_element'."); }
if (CB_Collisions.isPointTouchingElement(myPoint.x, myPoint.y, element)) { CB_console("The point is touching (maybe over) the element whose ID is 'my_element'."); } //Also if they are adjacent (next to each other).
//A rectangle and a DOM element (considered a rectangle):
if (CB_Collisions.isRectangleOverElement(20, 30, 100, 80, element)) { CB_console("The rectangle whose left upper corner coordinates start at (20, 30) and whose width is 100 and height is 80 is over the element whose ID is 'my_element'."); }
if (CB_Collisions.isRectangleTouchingElement(20, 30, 100, 80, element)) { CB_console("The rectangle whose left upper corner coordinates start at (20, 30) and whose width is 100 and height is 80 is touching (maybe over) the element whose ID is 'my_element'."); } //Also if they are adjacent (next to each other).
//Two DOM elements (considered a rectangle):
var element2 = CB_Elements.id("my_element_2");

//A point and a circle:

//A point and an ellipse:

//Two rectangles:
if (CB_Collisions.isRectangleOverRectangle(20, 30, 100, 80, 50, 70, 120, 90))
{
CB_console("The rectangle whose left upper corner coordinates start at (20, 30) and whose width is 100 and height is 80 is over the rectangle whose left upper corner coordinates start at (50, 70) and whose width is 120 and height is 90.");

For collisions with the mouse cursor, you can use the CB_Mouse static class. To get more information, read the Mouse topic of the basic tutorial.

Check the API documentation to read more about the CB_Collisions static class.
